All Implemented Interfaces:

AbstractIndexFieldData.PerValueEstimator
```
public class NonEstimatingEstimator
extends Object
implements AbstractIndexFieldData.PerValueEstimator
```
Estimator that does nothing except for adjust the breaker after the field data has been loaded. Useful for field data implementations that do not yet have pre-loading estimations.

Modifier and Type	Method and Description
`void`	`afterLoad(org.apache.lucene.index.TermsEnum termsEnum, long actualUsed)` Possibly adjust a circuit breaker after field data has been loaded, now that the actual amount of memory used by the field data is known
`org.apache.lucene.index.TermsEnum`	`beforeLoad(org.apache.lucene.index.Terms terms)` Execute any pre-loading estimations for the terms.
`long`	`bytesPerValue(org.apache.lucene.util.BytesRef term)`

public long bytesPerValue(org.apache.lucene.util.BytesRef term)
```
    Specified by:
    
    bytesPerValue in interface AbstractIndexFieldData.PerValueEstimator
    
    Returns:
    
    the number of bytes for the given term

public org.apache.lucene.index.TermsEnum beforeLoad(org.apache.lucene.index.Terms terms)
                                             throws IOException
```
    Description copied from interface: AbstractIndexFieldData.PerValueEstimator
    
    Execute any pre-loading estimations for the terms. May also optionally wrap a TermsEnum in a RamAccountingTermsEnum which will estimate the memory on a per-term basis.
    
    Specified by:
    
    beforeLoad in interface AbstractIndexFieldData.PerValueEstimator
    
    Parameters:
    
    terms - terms to be estimated
    
    Returns:
    
    A TermsEnum for the given terms
    
    Throws:
    
    IOException -

```
    Description copied from interface: AbstractIndexFieldData.PerValueEstimator
    
    Possibly adjust a circuit breaker after field data has been loaded, now that the actual amount of memory used by the field data is known
    
    Specified by:
    
    afterLoad in interface AbstractIndexFieldData.PerValueEstimator
    
    Parameters:
